viirusetõrjeile

Viirusetõrjeile, often referred to as antivirus software, is a type of computer program designed to prevent, detect, and remove malicious software, commonly known as malware. Malware encompasses a broad range of threats including viruses, worms, Trojans, ransomware, spyware, and adware. Antivirus software works by scanning files and programs for known patterns of malicious code, called signatures. When a suspicious file is found, the antivirus program can then quarantine or delete it, preventing it from causing harm to the computer system.

Beyond signature-based detection, modern antivirus solutions also employ heuristic analysis. This method examines the behavior of programs to identify suspicious activities that might indicate a new or unknown threat, even if a specific signature doesn't exist. Real-time scanning is another crucial feature, continuously monitoring system activity and incoming files to block threats as they emerge. Regular updates are essential for antivirus software to remain effective, as new malware threats are constantly being developed. These updates provide the software with the latest virus signatures and behavioral detection patterns.

Antivirus software is a fundamental component of cybersecurity for individuals and organizations. It helps protect sensitive data from theft, prevents system disruption, and safeguards against financial loss due to malicious attacks. While not a foolproof solution against all cyber threats, it significantly reduces the risk of infection and is a vital first line of defense.
